Screw lift lubrication problems following analysis of the relationship between temperature and kinematic viscosity of the lubricant of the gear used, the N320 extreme pressure gear oil viscosity-temperature characteristics. Kinematic viscosity is calculated based on the experience of 65 degrees with the temperature of the lubricating oil formula. By the formula t = 50 (50 / t) n have 65 = 50 (50/65) 3.1 = 180mm2 / S = 79.8mm2 / S = 80mm2 / S where t when the temperature t of the kinematic viscosity of the oil temperature of 50 degrees 50 n When the kinematic viscosity of oil to take the N320 in the index n = 3.1 to calculate the extreme pressure gear oils 40 = 320mm2 / S corresponding to 50 = 180mm2 / S40 = 140mm2 / S corresponding to 65 = 80mm2 / S according to the results shown in EP N320 gear oil viscosity-temperature diagram tp screw lift, shaft hoisting gear by opposing the use of N320 intermediate pressure gear oil viscosity changes with temperature and viscosity-temperature diagram calculation, apparent, when the temperature rises from 40 degrees to 65 degrees lubricating oil viscosity from 320mm2 / S dropped 140mm2 / S screw lift, lower viscosity values ??3180mm2 / S. This shows that as the temperature increases, the lubricant heated spiral screw lift, worm reducer intensified its thermal motion of molecules, cohesion decreases, so that the viscosity of the lubricant oil significantly decreased, so that the lubricating properties of the lubricating oil is significantly reduced. 1. SJ worm screw lift Model: SJ type is the basic type of lifts, the input mode for the input shaft type SJD type of lift with motor flange type, namely input flange type 2. SJ SJ input worm screw lift Input three ways: I type for RHS input type input for LHS II Type III biaxially input SJD input mode there are four: Type I Type II for the right to the left flange input flange for the right input type III Direct double into the IV-type double into the left-Direct 3.SJ worm screw lift screw head screw head in the form of four forms: R-type (cylindrical) H-type (flat head type) S-type (thread type) T-type (flange type) 4.SJ worm screw lift installation Type A - Type D rotating screw moves up - screw type B does not rotate downward move - move down the E-type rotary screw - rotating screw nut to move up C-type - screw moves up without rotating the F-type - screw moves downward rotation of the nut 5.SJ worm screw lift specifications by lifting force (t T): 2,3, 5,10,15,20,30,40,50,100 ton dozens.
